Randers' "most likely scenario" reveals a peak in the world population in the early 2040s at about 8.1 billion people, followed by decline.

[141] However, neo-Malthusians point out that fossil fuels provided the energy for the Green Revolution, in the form of natural gas-derived fertilizers, oil-derived pesticides, and hydrocarbon-fueled irrigation, and that many crops have become so genetically uniform that a crop failure in any one country could potentially have global repercussions. During the 2nd millennium, each doubling took roughly half as long as the previous doubling, fitting the hyperbolic growth model mentioned above. Before the invention of agriculture, for example, the human population was estimated to be around 15 million people at most. Here's an interesting perspective on today's world population in 2016: today's world population (~7 billion) is approximately 6% of the estimated 110 billion who have ever lived.
